What's new in this version:

New features and enhancements:
- mkvmerge: chapters: added support for specifying MPLS files with`--chapters`, too, not just as regular source files. The documentation stated this was possible already, but that wasn't actually the case.
- MKVToolNix GUI: multiplexer: added a progress dialog that is shown duringfile identification.
- MKVToolNix GUI: jobs: the status bar now differentiates between numbers of warnings/errors that occurred in the current session and those that occurred before the current session

Fixed:
- mkvmerge: AAC parser: LOAS/LATM streams: if the first `AudioSpecificConfig` element is not found within the first LOAS/LATM frame, `mkvmerge` will no longer discard the frames before it but defer parsing them until after it has found the AudioSpecificConfig` element.
- MKVToolNix GUI: job queue: fixed the GUI crashing when re-ordering the jobs in the job queue

Build system changes:
- The bundled `fmt` library was updated to v10.2.1
